“One Hour Heating & Air and Michael P. Jordan specifically were incredibly helpful. I called OHH&A early Friday morning when I realized my heating was down. The agent walked me through troubleshooting to see if we could fix the issue without sending a service technician. When I was able to get the system running, they had a technician (Michael) at my home later that morning. He temporarily fixed the issue so we had heat through the weekend, and came back on Monday to finish up the full install of our new thermometer. I had an incredible experience from start to finish, and all for a reasonable price given it was an emergency. I HIGHLY recommend using One Hour Heating & Air for any HVAC related issues, especially emergencies!”

“I couldn’t be happier with my new furnace installation. After my old unit failed in middle of winter. I called multiple companies to give a quote, one company pressured us so much we were very put off the by whole process. I called One hour and Krunal, the manager, came that night to assess the situation. He provided us with a fair and transparent quote without feeling like we were being pressured. Krunal and the technicians arrived the next day with a new furnace and were incredibly professional. We also decided to get the oxyquantum LED and electronic air filter. The difference in my home's comfort and air quality was noticeable within the hour. If you are looking for reliable and personable HVAC service, I highly recommend this team for their expertise and exceptional customer service!”
